Subject: [PATCH] Input: goodix - support gt9147 touchpanel

From: Yannick Fertré <[email protected]>

Add support for it by adding compatible and supported chip data
(default settings used).
The chip data on GT9147 is similar to GT912, like
- config data register has 0x8047 address
- config data register max len is 240
- config data checksum has 8-bit

If it is compatible with gt912 then the driver does not need another
compatible in the code I think. Rob will tell more.

Hello,
Dmitry,
I forgot to modify the binding to declare the new compatible "gt9147".
Rob,
can I modify the binding without converting it first to yaml?

Best regards

Yannick Fertr?
